20.500.12556/DKUM-35868 Singing of Neoconocephalus robustus as an example of deterministic chaos in insects We use nonlinear time series analysis methods to analyse the dynamics of the sound-producing apparatus of the katydid Neoconocephalus robustus. We capture the dynamics by analysing a recording of the singing activity. First, we reconstruct the phase space from the sound recording and test it against determinism and stationarity. After confirming determinism and stationarity, we show that the maximal Lyapunov exponent of the series is positive, which is a strong indicator for the chaotic behaviour of the system. We discuss that methods of nonlinear time series analysis can yield instructive insights and foster the understanding of acoustic communication among insects. chaotic systems chaos time series time series analyses insect sounds katydid kaotični sistemi kaos nelinearni sistemi časovne vrste analize časovnih vrst zvoki insektov ameriška kobilica true true true Angleški jezik Slovenski jezik Članek v reviji 2012-06-07 12:30:22 2012-06-07 12:30:22 2024-05-28 13:50:01 2021-04-15 03:35:34 2007 0 0 str. 797-804 št. 4 Letn. 32 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0250-5991 544.022.3 15661832 10.1007/s12038-007-0081-5 0250-5991 URN:SI:UM:DK:B6ZISUFX RAZ_Benko_Tina_P._i2007.pdf RAZ_Benko_Tina_P._i2007.pdf 1 7FFA31DE7D34A877486121F211C1FBDD 7fb6f4efd85af4c74bd5c88096f8ed34d4a90f13a42cbfe3eaa2b0462ad287eb 043ef8cf-7c08-11eb-bb7a-00155d0001ca 20.500.12556/dkum/b900481d-3f80-42a1-9eb3-2a57f195eae4 https://dk.um.si/Dokument.php?lang=slv&id=46894 http://link.springer.com/10.1007/s12038-007-0081-5 1 https://dk.um.si/Dokument.php?lang=slv&id=46895 Fakulteta za naravoslovje in matematiko 0 0 0
